To all wkomnimdy concern:

' Be it known that I, CHARLES H. DE'RHAM, a

citizen ofrthe'United-States, residing at Corunnat in the county ofShiawassee, State of 5 Michigan, haVe.-invented certain new and use.

standard 27. This standard 27 is supported by a bracket 1l, similar tothat which supports the standards of the blocking-knives, said .standard27 being secured in place by the bolts 28, which pass through thesides-of said brackets and throughsaid standard.

By loosening the bolts 13, which secure the brackets carrying thestandards of the blocking-knives and rotary disks, said brackets may beadjusted longitudinally of the beam 9 to regulate the space between eachpair or set of the rotary disks and to enable.v the blocking-knives tobe adjusted laterally with respect to the position of said disks, sothat the sharpened forward edge 30 of said standard may stand contiguousto the face of the disk, and thereby prevent the wedging of anysubstance between said disk and standard.

` It'will be observed that the rotary disks or cutters 24 are arrangedin pairs and the disks of each pail` spaced .by the interposed hub 26from two to three inches apart, Aas desired.,

It will also be observed that the blockingknives 18 aresopositioned asto occupy the space between the outer faces of the opposed disks of eachpair. By 'this arrangement as the .machine is drawn across the field thesurfaceof the earth is cut through on each side of the beet-plants itisdesired to cultivate, and the knives 18 block out the remaining plantsbetween said pairs of disks, thereby leaving of the row only thoseplants which remain undisturbed between each pair ot' the rotary disksas the machine is .drawn along.

The rotary`dis'ks cutting into the earth as they do on'each side of theplants sever all earth crusts and clods, so thatthe blockingknives4 intheir passage through theground cannot tear the earth and injure theplant that is left between said disks,'whil e said disks serve as aguard to prevent clods from shoving against the plants and the earthwhich is l thrown up by the'blocking-knives or cultivators from fallingthereon, enabling a large area of beets'to be blocked in aperfect mannerwithin a comparatively short time, thereby elfecting a great saving oflabor.

The handles 29, which are shown as partly' i' broken away, are attachedto the draft-bars 7 and enable the operator tocontrol the machine. Bymeans of the engaging hooks 6 at the forward end ot' said 'draft-barsand the pivotal connection-B lbetween the rear horse dcfiect from theline of said row.

ends of said bars and the beam 9 said beam and the cutters carriedthereby may be swung laterally of thc machine, so as to maintain thecircular cutters at all timos straight with the row that is beingblocked out should the It will also be evident that the 4operator bymeans of the handles may force the cuttingdisks into the ground wherethe ground is hard and when encountering soft ground may raise thecutters, so as to prevent them from cutting too deep.

When used as a cultivator, the blockingknives maybe changed for a shovelor tooth of any suitable form, will be understood.

Having thus fully. set forth my invention,

what I 'claim as new, and desire to secure by Letters Patent, is i ,Y

1. In a machine for the purpose set forth, the combination with thetransportable frame, of the rotary cutters adapted to eut through thesurface of the ground on each sideoi' the plant, said rotary cuttersbeing positioned 'in the rear of the transportable frame, a flexibleconnection between said cutters and frame and the blocking-knivesinterposed between said rotary cutters to sever the plants between them.

2. In a machine for the purpose set forth,A the combination ot' therotary cutters arranged in pairs to straddle the plant to beleft forcultivation, and the lateral blocking-knives interposed between thepairs of rotary cutters, said knives being positioned to work betweensaid cutters in transverse alinement IOO blocking-knife vextendingbetween the faces' j of said disks, each knife being independently 4movable in the arc of a circle and independently adjustablei'fertically.

' 4. ,'In a'beet-blockng machine, the combi- IIO nation of the portableframe, the rotary cuttingdisks arranged in pairs, and mounted upon saidframe, the blocking-knives interposed between the outer faces of thedisks of each pair, said knives being adjustable independ ently of-saiddisks, a transportable frame,

and a flexible connectionbetween said frames. 5. In a beet-blockingmachine, the combination with the axle and transporting-wheels,

of the transverse beam loosely connectedvto said axle in the rearthereof, rotary cuttingdisks laterally adjustable on the beam andarranged in pairs te straddle the beet-plants.,

and the adjustable blocking-knives interposed and extending between eachpair of disks sub- 5 stantially asset forth. Y

6. In abeet-bloeling machine, the combiu nation with thetransporting-Wheels and the beam connected tlleiewith, of the opposeddcutting-disks secured in pairsto said beam', a IO blockingdnifelnterposed between each pau' of said disks eaeb. knife being adjnsabievesti cally and having independent mpvenienl; in the ae of a cirelebochange 'the angle ef the blade.
